The Xerox R&D company PARC and Arizona State University's Flexible Electronics and Display Center (FEDC) has recently announced the successful manufacture of a flexible X-ray detector prototype, which they claim is the world's largest. The prototype measures 7.9 diagonal inches, made of advanced thin film transistors (TFTs) and will be used to advance the development of flexible X-ray detectors in lightweight, thin and ultra-rugged devices.

The TFT and PIN diode processing was done on the 470mm by 370mm Gen II line at the FEDC. This device showcases the FEDC's successful scale up to GEN II, and the ability to produce sensors and displays using TFTs in standard process flows with the FEDC's proprietary bond/de-bond technology.

PARC has built the system incorporating a component built by FEDC. The above image is an x-ray image taken by the system.

The system design and integration was done at PARC. The flexible x-ray sensor was coupled to a flexible electrophoretic display and electronics to provide a self-contained, direct-view unit (including battery, user-interface and software). This system shows PARC's capability to build user-defined prototype systems incorporating novel device physics, materials and technology. PARC has extensive experience in building large-area electronic systems, display and backplane prototypes, and organic and printed electronics.
